@Tridac - "Teach users to delete any emails that they don't recognise"
So do you open the email with the subject, "Please change my appointment"? Anyone whose job is to interact with the public can be targeted by a suitable email. Sure, dumping any email client with scripting support is good (if you disable it, do you trust that the next update doesn't turn it back on silently, for whatever reason), but how do you force the public to only send plain text?
